Bulletin No. 88 - The Relation Of Smelter Smoke To Utah Agriculture, John A. Widtsoe
Bulletin No. 88 - The Relation Of Smelter Smoke To Utah Agriculture, John A. Widtsoe
UAES Bulletins
Utah's position among the great commonwealths depends upon the degree of development of the agricultural industry of the State. As a producer of wealth, however, the mining industry exceeds agriculture. The total annual value of Utah farm products is about $17,000,000.00, while the total output from the mines is valued at $34,000,000.00. The operation of the mines, reduction mills and smelters necessitates the employment of large numbers of people, who swell the population of the State, and consume a large part of its agricultural products. Utah, which is an inland State, possessing as yet few large manufacturing enterprises, finds the …

Bulletin No. 82 - Feeding Beet Pulp To Steers And Sheep, R. W. Clark
UAES Bulletins
For the last two winters feeding experiments have been carried on by this Station to ascertain the value of beet pulp and beet molasses as food for sheep and steers. In a feeding test made with sheep two years ago, the results of which are reported in bulletin No. 78, sugar beet pulp and sugar beet molasses gave profitable returns. When lucern and pulp were fed, one pound of gain was made from 7.95 pounds of lucern and 17.86 pounds pulp. One hundred pounds of increase was made at a cost of $2.48 and pulp had a value of $1.86 …

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.13, William H. Ashmead

This family, although quite distinct, is closely allied to the two which follow-the Myrmosidae and the Mutillidae-and it will probably be difficult for the student to separate at once the wingless females from some in the families mentioned. Some authorities, having been unable to find good characters to separate these wasps, have classified all together as a single large family under the name .Mutillidae; but I think incorrectly so.

By most systematists this family is still classified with the Scoliidae, although separated as a distinct family by the Swedish entomologist, C. G. Thomson, as early as 1874. I agree with Thomson, and believe these wasps form a distinct family, easily recognize d by the characters made use of in my table of families.

M. E. Haug a donne, en 1901, au laboratoire d'Entomologie un certain nombre d'Hymenopteres recoltes par lui dans le Congo francais, dans le has Ogooue , pays compris entre Lambarene et le littoral de la mer. Parmi ces insectes, il se trouve trois especes nouvelles dont voici les descriptions.

Les Hymenopteres don’t il est question dans cette etude appartiennent au genre Vespa, lequel fait partie de la famille des Vespides. Ceux-ci terminent un des rameaux de l’arbre philogenetique des Hymenopteres, don’t le tronc est forme par ces insectes don’t les larves purvoient ells-memes a leur nourriture et vivent de matieres vegetales. Au fur et a mesure que l’on s’eleve de la souche aux rameaux, on reconnait que l’instinct s’est modifie avec la maniere de vivre.
